=============Rooney=============
This line-up, IMO, would win a lot of silverware. However, if we were to get Hazard and Kagawa, it would mean probably getting rid of either Young, Nani or Valencia.
Or SAF could try and convert Kagawa into a box to box midfielder. Then the lin-up would probably look lik this:
=============De Gea=============
Rafael====Smalling====Vidic=====Evra
=========Kagawa====Carrick=======
Nani==========Hazard========Young
=============Rooney=============
Kagawa could rotate with Cleverley and Carrick rotate with Strootman.
